External determinants and daily outcomes of self-leadership

The thesis aims to investigate the determinants and outcomes of self-leadership. First objective is to explore the potential determinants of self-leadership. Another objective is to examine role of daily self-leadership on attitudes and extra-role behaviors such as constructive voice, organizational citizenship behaviors (OCBs), and work engagement among employees. Two studies were conducted regarding the proposed model. Applying a mixed-methods approach, Study 1 consists of qualitative interviews to explore the determinants of self-leadership, while Study 2 utilizes a daily-diary design with 180 employees over 5 consecutive workdays. The findings depending on the multilevel analysis revealed that daily self-leadership has positive direct paths to daily constructive voice, OCBs (OCBI-toward individuals and OCBO-toward the organization), and work engagement. Moreover, daily positive affect has been found to mediate the path between daily self-leadership behaviors and daily constructive voice and OCBs, while daily job crafting (cognitive and relational) has mediated the path between daily self-leadership and individuals' daily work engagement. The qualitative study highlighted the potential role of work design characteristics in explaining self-leadership behaviors, as well as exploring the additional determinants of the self-leading process. Collectively, the results emphasize the importance of daily self-leadership fluctuations in explaining positive daily variations in employee behaviors and attitudes and elucidate the underlying mechanisms.
